TeSys U

TeSys U Compact All-in-One Motor Starter & Protection Controller

Reliable motor control begins with a solution that integrates protection, switching, and monitoring, and the TeSys U range from Schneider Electric delivers exactly that. Designed for simplicity, space-saving, and robust performance, TeSys U brings together motor disconnect, branch-circuit protection, starter, and overload into a single unit. Featuring wide current ranges, high fault-rating capacity, and modular expansion options, it’s an ideal choice when you want streamlined motor control without compromising on functionality.

Simplified Selection, Reduced Wiring & Panel Space Savings

TeSys U’s design philosophy centres on consolidation: a single power base plus control module replaces traditional breaker + contactor + overload relay setups. According to Schneider Electric documentation, the model covers motor applications up to 20 hp at 480 V (≈ 32 A) and provides a short-circuit current rating of 65 kA in wye configuration. With an optional current limiter, this rating rises to 130 kA in delta. With just six basic references covering 0.15 A to 32 A, the TeSys U range significantly streamlines part selection compared with traditional systems. Less wiring means fewer sources of error, faster build times, and a smaller enclosure footprint, key advantages for panel builders and OEMs. 

Modular, Flexible & Built for Monitoring

Although TeSys U provides integrated protection and switching, it doesn't compromise on advanced features. The product supports a stack of optional modules: communication interfaces, fault-log modules, parameter monitoring, remote reset, phase-loss detection, and more. You’ll find versions offering up to 15 million mechanical operations and cycle rates up to 3600 per hour for demanding applications. For example:

• A built-in mirror contact allows auxiliary monitoring of motor status.
• Sealable control units with lock-off in the OFF position support safe maintenance. 
• Remote diagnostics: Fault logs store the last five trips, enabling proactive service and plant uptime improvement.

Broad Supply Voltages, Application Coverage & Safety Compliance

TeSys U accommodates a wide range of control voltages and motor sizes. For instance, the control unit options support AC or DC coils, and there are both standard and “advanced” modules for everything from basic ON/OFF to networked operation. Power-base ratings cover, in one referencing table, up to 32 A and motor power up to 20 hp at 460 V in three-phase machines. The integrated protection includes thermal overload, short-circuit, phase imbalance, and phase loss functions, allowing TeSys U to address some 80>#/b### of typical motor protection and control needs in industrial installations. 

Why Choose TeSys U for Your Motor Control Application?

When specifying motor starters or control blocks, ease of installation, compactness, and performance matter. 

TeSys U delivers:

• A simplified bill of materials (single device for multiple functions)
• Faster installation and commissioning thanks to fewer components and pre-wired modules
• Better panel utilisation through reduced width and fewer trains of parts
• Enhanced reliability via integrated protection and monitoring features
• Scalable architecture: from basic starters through to networked motor control with diagnostics
